BackgroundThe incidence of dengue fever is on the rise in tropical countries. In Sri Lanka, nearly 45,000 patients were reported in 2012. With the increasing numbers, rare manifestations of dengue are occasionally encountered. We report a patient who presented with bilateral cerebellar signs as the presenting feature of dengue.Case presentationA 45-year-old previously healthy female from the suburbs of Colombo, Sri Lanka presented with an acute febrile illness associated with unsteadiness of gait. Clinical examination revealed a scanning dysarthria and marked horizontal nystagmus with bilateral dysmetria, dysdiadokokinesia and incordination more prominent on the right. Her gait was wide-based and ataxic with a tendency to fall to the right more than to the left. Dengue nonstructural protein antigen 1 test and IgM antibody testing both became positive indicating acute dengue infection. She recovered from the febrile episode within 9 days since the onset of fever but cerebellar symptoms outlasted the fever by one week. The magnetic resonance imaging of brain was normal and cerebellar signs resolved spontaneously by day 17 of the illness.ConclusionsCerebellar syndrome in association with dengue fever has been reported in only four instances and our patient is the first reported case of dengue fever presenting with cerebellitis as the first manifestation of disease. This case report is intended to highlight the occurrence of acute cerebellitis as a presenting syndrome of the expanding list of unusual neurological manifestations of dengue infection.
Hump-nosed viper bites are frequent in southern India and Sri Lanka. However, the published literature on this snakebite is limited and its venom composition is not well characterized. In this case, we report a patient with thrombotic thrombocytopenic purpura-like syndrome following envenoming which, to the best of our knowledge, has not been reported in the literature before. A 55-year-old woman from southern Sri Lanka presented to the local hospital 12 hours after a hump-nosed viper (Hypnale hypnale) bite. Five days later, she developed a syndrome that was characteristic of thrombotic thrombocytopenic purpura with fever, thrombocytopenia, microangiopathic hemolysis, renal impairment and neurological dysfunction in the form of confusion and coma. Her clinical syndrome and relevant laboratory parameters improved after she was treated with therapeutic plasma exchange. We compared our observations on this patient with the current literature and concluded that thrombotic thrombocytopenic purpura is a theoretically plausible yet unreported manifestation of hump-nosed viper bite up to this moment. This study also provides an important message for clinicians to look out for this complication in hump-nosed viper bites since timely treatment can be lifesaving.
BackgroundTakotsubo cardiomyopathy is characterized by transient systolic dysfunction of the apical and mid segments of the left ventricle in the absence of obstructive coronary artery disease. Intraventricular thrombus formation is a rare complication of Takotsubo cardiomyopathy and current data almost exclusively consists of isolated case reports and a few case series. Here we describe a case of Takotsubo cardiomyopathy with formation of an apical thrombus within 24 h of symptom onset, which has been reported in the literature only once previously, to the best of our knowledge. We have reviewed the available literature that may aid clinicians in their approach to the condition, since no published guidelines are available.Case presentationA 68-year-old Sri Lankan female presented to a local hospital with chest pain. Electrocardiogram (ECG) showed ST elevation, and antiplatelets, intravenous streptokinase and a high dose statin were administered. Despite this ST elevation persisted; however the coronary angiogram was negative for obstructive coronary artery disease. Echocardiogram revealed hypokinesia of the mid and apical segments of the left ventricle with typical apical ballooning and a sizable apical thrombus. She had recently had a viral infection and was also emotionally distressed as her sister was recently diagnosed with a terminal cancer. A diagnosis of Takotsubo cardiomyopathy was made and anticoagulation was started with heparin and warfarin. The follow up echocardiogram performed 1 week later revealed a small persistent thrombus, which had completely resolved at 3 weeks.ConclusionThough severe systolic dysfunction is observed in almost all the patients with Takotsubo cardiomyopathy, intraventricular thrombus formation on the first day of the illness is rare. The possibility of underdiagnosis of thrombus can be prevented by early echocardiogram in Takotsubo cardiomyopathy. The majority of reports found in the literature review were of cases that had formed an intraventriclar thrombus within the first 2 weeks, emphasizing the importance of follow up echocardiography at least 2 weeks later. The management of a left ventricular thrombus in Takotsubo cardiomyopathy is controversial and in most cases warfarin and heparin were used for a short duration.Electronic supplementary materialThe online version of this article (doi:10.1186/s12872-017-0616-0) contains supplementary material, which is available to authorized users.
IntroductionPosterior reversible encephalopathy syndrome is a clinicoradiologic entity characterized by headache, seizures, decreased vision, impaired consciousness and white matter oedema in bilateral occipitoparietal regions. Hypertensive encephalopathy, eclampsia, immunosuppressive/cytotoxic drugs, organ transplantation, renal disease, autoimmune diseases and vasculitides are reported risk factors of posterior reversible encephalopathy syndrome. Reports of cyclophosphamide-induced posterior reversible encephalopathy syndrome are rare and occurred in a background of renal failure, fluid overload or active connective tissue disease.Case presentationWe report a case of posterior reversible encephalopathy syndrome developing as a direct consequence of intravenous cyclophosphamide therapy in a 33-year-old normotensive Sri Lankan woman with lupus nephritis but quiescent disease activity and normal renal function.ConclusionsThis case report highlights the need for awareness and early recognition of this rare but serious adverse effect of cyclophosphamide that occurred in the absence of other known risk factors of posterior reversible encephalopathy syndrome and that early appropriate intervention leads to a good outcome.
ObjectivesCurrent guidelines suggest that patients presenting with the first seizure should be assessed by a specialist, preferably with investigations such as electroencephalography and imaging to reach a definitive diagnosis. We conducted a cross sectional study among patients with confirmed epilepsy, at a tertiary level neurology clinic in Sri Lanka with the aim of assessing delays in first contact with a medical doctor and in performing key investigations after the first seizure.ResultsMajority had sought medical attention within 24 h of the first seizure (71.2%) and had seen a specialist within the 1st week since the seizure (61%). Also a significant proportion had completed key investigations such as electroencephalography (63.2%) and brain imaging within a month (51%) since the first medical consultation. Of many socio-demographic and illness related factors examined, only a non-generalized tonic–clonic presentation was significantly associated with delay in seeking medical help.
